Electromagnetic waves
Electromagnetic waves, if it was mechanical, something would literally have to make them!

summer solstice
blah
true :)
it protects us from the suns UV rays
It is the cause of the differences in temperature at the equator and North and South Poles.

Electromagnetic waves
The sun is a mechanical wave because it doesn't have radio waves in it and it doesn't have spectrum energy, unlike electromagnetic energy.
One health risk i know of is leukemia from the suns ultraviolet light, which is an electromagnetic wave. im sure there are tons of other health risks from other electromagnetic waves such as gamma rays and x-rays.
Waves
the tranfer of energy from the sun in form of electromagnetic waves is known as radiation.
The UV rays of the sun are a part of the electromagnetic spectrum. These are high energy radiations. They build and destroy ozone both.
Radio waves ... including microwaves ... and X-rays are different only in wavelength (frequency). The sun radiates all of them.
Electromagnetic energy makes use of the sun rays. Plants and other things use the sun rays to grow.
Most of it travels to Earth via light, and similar electromagnetic waves.
Since radiation is done by electromagnetic waves, it can travel through space. i.e no matter is required. That way you can heat up objects through space. Or, for example, the earth gets heated by the suns electromagnetic waves.
No, the sun radiates light, and other electromagnetic radiation,continuously - even at night.
